JORGECABELLO
Product Engineer · Buenos Aires
Self-taught. Seven years building frontends at startups. From GSAP animations on Fiverr to monorepo architecture at a Series A company.
About
I taught myself to code in Venezuela and moved to Argentina in 2019. Started doing creative frontend work on Fiverr. GSAP animations, SVG stuff, the kind of sites that actually move.
Then I joined a startup as the second engineer, built the frontend from nothing, and stayed through Series B as the team grew to 30. After that, more startups. Always early, always building the thing that didn't exist yet. Right now I'm three years into a funded EdTech company where I went from frontend to leading the AI work.
React, TypeScript, and animation are my core. I build with Claude Code and Codex as daily collaborators. Custom tooling, multi-agent reviews, automated workflows. I also ship native apps in Swift on the side. Frontend is home.
Experience
Senior Software Engineer
Cometa · Series A · $12M raised · K-12 SaaS · React, Next.js, TypeScript, Turborepo
- Set up the frontend monorepo from early on: Turborepo, React Query, shared configs. Three apps run on it today.
- Built most of the core product surfaces: payments, invoicing, school management, reporting, data tables. The kind of work where you own entire features end to end.
- Built the AI chat interface (Jarvis). Streaming responses, conversation history, feedback, accessibility. The thing every team at the company uses daily.
- Kept the platform stable and fast as it scaled. Deployment pipeline, error tracking, performance. The boring stuff that makes everything else possible.
- Built the frontend for a support agent that handles 80% of incoming tickets. Streaming chat UI, feedback system, admin dashboards.
- Shipped the interfaces for RAG search and a SQL agent with per-school data isolation. Built the query UIs and dashboards that four non-technical teams use daily.
- Ran hackathons, lightning talks, and AI 101 sessions. Taught 50+ people across the company how to actually use these tools.

Stack & Tools

Backend
AI / Tooling
Native
AI-Native Workflow
I treat AI tools the way most engineers treat their IDE. They're part of the infrastructure. These are custom Claude Code skills I built to automate real workflows. Multi-agent coordination, browser automation, production pipelines.
/council
Multi-model code review. Sends my current context to Codex for an independent analysis, then compares both perspectives. Catches blind spots neither model finds alone.
/sentry fix
End-to-end production error resolution. Finds the error in Sentry, traces it to the code, applies a fix, opens a PR, and monitors the deploy for regressions.
/recall
Semantic search over 7,100+ files of past conversations and notes. Gives every new session full context from every previous one.
/finance
Browser automation that logs into my bank, pulls transactions, categorizes spending, and updates my financial tracking. Full Playwright pipeline.
/afip
Navigates Argentina's tax portal to generate export invoices. Form filling, validation, submission. All through browser control.
/light
Natural language control of Philips Hue lights. Mood presets, room awareness, bilingual commands. Hardware integration through Claude Code.
